Why proper planning matters on a new roof
One roof, not loose parts
We plan the roof as a full system so the details work together from day one.
Slate or tile guidance
The covering choice is matched to the build, not picked on looks alone.
Cleaner finished appearance
Early setting-out helps the new roof sit neatly on the building as a whole.
Building a roof system from the start
A new pitched roof is more than a top layer of slates or tiles. It is a full weatherproof build-up, with the supporting roof, underlay, battens, chosen covering and each junction working together. We install new pitched roofs in Plymouth for domestic projects such as new builds, extensions and larger property alterations where a completely new roof is needed. With CJ Roofing SW Ltd, the job is planned as one joined-up system, so drainage, detailing and the finished look are considered before the first covering goes on.


Planning the details before work begins
Slate and tile are the main routes, but the best choice depends on the roof pitch, loading, design and the appearance you want. We also plan the important details early, including ventilation, valleys, ridges, abutments, drainage and chimney positions where relevant. A quote from CJ Roofing SW Ltd sets those points out clearly, which helps avoid the kind of late surprises that can slow a project down. Careful installation from the start gives the roof a better chance of staying weather-resistant and looking coherent across the whole build.
Frequently asked questions
Is this service suitable for extensions and new builds?
Yes. We take on new pitched roof work where a full roof system is required, including domestic extensions and substantial alterations as well as newly built homes. The main point is that the roof needs planning and installation from the beginning rather than repair of an existing covering.
Can you help us choose between slate and tile?
Yes. We talk through roof pitch, structural loading, design and appearance so the choice is practical as well as attractive. That way, you are not left guessing which covering suits the build, and the decision can be made before installation starts.
Why do roof details need planning so early?
Because features such as valleys, ridges, abutments, drainage and ventilation affect how the whole roof performs. If those points are left until late in the job, the roof can become harder to finish neatly. Early planning helps the work run more smoothly and the result look more settled.
